I suggest in the meantime until you can see the doctor on your condition that you at least begin eating healthy foods. Start by cutting out the items that do the most damage to shedding pounds and feeling good about yourself.
With that being said you need to cut out carbohydrates, that includes the following; bread, potatoes, pasta, and rice. If it is made with flour do not eat it.
Secondly, cut out ALL SUGARS. This is not a condition of "ok I've been good all day, one piece of chocolate, or one cookie won't kill me". This is to get control of how your insulin responds to food that you place in your vessel.
You have to ELIMINATE it completely. It is only through such change can you at the VERY LEAST start to build healthy and positive attitudes toward the foods you eat, and the amount.
I do not care if you eat 3 chickens in one setting, as long as there is no barbeque sauce on it, or some other sauce to make it taste more appealing. You can eat it. No soda pop, if you want a beverage other than water, then go get Stevia extract, carried by most stores now. Make some stevia lemonade. Buy drink products made with stevia. Vitamin water Zero (not the greatest example but at least better than diet coke). Begin training your mind and YOUR body to get used to these types of things and soon it will become habit.
You are living and acting on habitually bad habits now, so begin your journey to a healthier you by making those steps a FOCUSED part of your goals. That in itself will eliminate fast food, it will eliminate processed foods, it will make you cook meals with higher vegetable count (not the starchy filler of potatoes and the like), it will teach you to cook lean meats with a variety of healthy spices to season your food so that it is not only healthy but good tasting.
There are potentially deeper issues here at work as well, since it sounds like you binge eat. So to help with that, start making large enough portions to feed your body, but no more so you are resistant to going back for seconds.Do not skip meals, in other words do not go all day not eating, and then binge at dinner time.
There are a wealth of ways to deter you from getting out of your bad habits, but the most IMPORTANT one is the will and determination that ONLY YOU can provide.
Once YOU make that choice none of the objections or reasons why you cannot move forward into a healthier YOU will hinder your progress.
Best of wishes, and not next week, or next year is a good time to make a change for the better, but NOW.
